<DIV><FONT face=Arial size=2>Due to Cameron's experience a while back, I had
avoided lithium batteries when they first came out. It's like being the first
one to buy any new technology, you're taking a great risk. I'd rather use tried
and proven stuff for equipment.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>With that being said, I now use a 1600mah LiPoly
pack from Batteries America. It weighs about 3 ounces with the 6v regulator, and
has oodles of power. With an OS I could get 12-15 flights on P-07, with a DZ160
I can get about 8 comfortably. Vibration makes a huge difference in battery
drain.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>it's pretty cheap and I've been using them for
about a year and a half now with zero problems. I do charge it in the plane,
however my charging habits are a bit different...I always babysit my plane. I
charge it on the wall in the shop where I have a fire extinguisher while I'm
building or on the computer. When I'm on the road I charge it either on the
ground, or in a motel room on the floor with me sitting right over it the whole
time. Hundreds of charge cycles, zero issues.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I use a standard great planes Triton charger
plugged into a JR charge switch.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It's light, it's cheap, and it works really
well.</FONT></DIV>

<DIV>Vicente,</DIV>
<DIV> </DIV>
<DIV>For the 30 years I've been using rechargeably batteries in RC, I have had
one nicad and one nimh vent and smoke - no fire, no explosion, but definitely
very hot and smoldering. Certainly hot enough to have caused a fire if
in a different environment. In both cases, I was close enough to smell
the problem and remove the batteries from the plane without damage to anything
other than the batteries (and maybe some charred/scorch marks).</DIV>
<DIV> </DIV>
<DIV>Point being, ANY battery can have a problem. The higher the energy
density and larger the amount of energy stored, the greater the potential
problem. And it would seem in RC applications, the more mature battery
technologies are the safest for our typical use, but some would advocate never
charging any battery unsupervised.</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>

<DIV>Here are the safety instructions for TP batteries web site: </DIV>

<DIV>I could not find the safety instructions on the Duralite web
site. </DIV>
<DIV> </DIV>
<DIV>Here the safety instructions from Fromeco web site:</DIV>

<DIV> </DIV>
<DIV>The problem I have is that I don't have time to baby sit while the
battery are charging. I try to do it with my small electric planes and
I can not imagine babysitting all my planes while charging.
Probably this is the only issue I have in regard lithium
batteries. Do we really need to follow this instructions? If
not, the manufactures will need to take the risk and take those instructions
out from the web sites.</DIV>

<DIV><FONT face=Arial color=#000000 size=2>I had bought a few NMP 2400 mAh
packs from Central last year. I don't see them on their website now
though.</FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>I am apprehensive to go Li-Poly
due to the packaging and possibility of damage and fire. The Li-Ion is in
a metal can that can shield it from physical damage. Using the wrong
charger on the other hand would still be an issue. </FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>The Li-Ion packs are lighter
than a NiCad or Ni-Mh packs so you gain a weight savings and they need
less maintenance than the aforementioned battery types. </FONT></DIV>
<DIV><FONT face=Arial color=#000000 size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#000000 size=2>I even made a pack to replace
the Ni-Mh pack in my Multiplex EVO and it is holding up well.</FONT></DIV>
